Red Socket and Blue Basher are the same robot with different colours and a slightly different part count. Socket has 123 parts, Basher has 139. Both perform identical functions. The only real reason to choose one over the other is which colour you prefer or which has the better price on the day you buy. If you want both robots together, they interact with each other which is where the real fun starts.

2 Same Robot, Different Look
The most important thing to understand about the Meccano Micronoid range is that Red Socket and Blue Basher are functionally identical. Every play mode, every programming feature, every interaction capability is the same across both robots. Choosing between them comes down almost entirely to colour preference and price on the day you buy.
Both robots use the same Meccano-style construction system — plastic parts connected with metal nuts and bolts using the two included hand tools. The finished robot stands approximately 18 cm tall, fits in the palm of an adult’s hand, and walks by rolling on wheels hidden inside its feet rather than walking on articulated legs. The head rotates independently of the body.
The official Meccano website confirms that all three Micronoids — Socket, Basher, and the third robot Switch — perform identical functions. The product description for each is virtually word for word the same. This is not a case where one robot has features the other lacks. They are the same product in different colours with slightly different styling details. For context on what programmable robot kits contribute to STEM learning, the National Science Foundation has documented how hands-on construction and programming toys develop problem-solving and engineering thinking in children.
3 How the Programming Actually Works L.I.M.
The programming system is called L.I.M. — Learned Intelligent Movement. It works through buttons on top of the robot’s head. You press record, then press the movement buttons (forward, left turn, right turn) in any sequence. Press play and the robot performs that sequence. If you speak into the robot while recording, it captures your voice and plays it back in a robotic tone.
The movement itself is jerky rather than smooth — this is a known characteristic of all Micronoids and worth setting expectations around. The robots move in short bursts rather than flowing motion. With practice you can get precise sequences, but there is a learning curve to understanding how far each button press actually moves the robot.
Three play modes cover different types of interaction:
- 8-Ball mode — ask a yes or no question out loud, the Micronoid responds with an answer in its own voice. Responses include “Oh yeah!”, “No, no, no” and various uncertain answers. Children find this genuinely amusing.
- Dance mode — play music near the robot and it dances to the beat. Leave it long enough in this mode and it starts playing its own music and dancing regardless.
- Autonomous mode — the robot does whatever it wants. It wanders around, whistles, laughs, passes wind, and turns its head at random. This mode has the most personality.
When two Micronoids are placed near each other, they detect each other and begin interacting — moving toward each other, dancing in sync, and making sounds that respond to the other robot. This is the feature that makes owning both genuinely worthwhile rather than just collecting both colours.

4 The Build Experience
Both Micronoids use plastic Meccano parts connected with metal nuts and bolts. The build is more fiddly than standard Meccano Junior sets and genuinely appropriate for ages 8 and up. Younger children will need adult help, particularly for the smaller connector pieces and the head mechanism.
Red Socket (123 parts) takes between 90 minutes and two hours for most builders. Blue Basher (139 parts) is reported to build slightly faster — around one to one and a half hours — despite having more parts, because the body panel design fits together more intuitively. This difference is minor and will vary by builder.
The instruction manual for both robots is clear and includes tips on how to use the programming system, which is helpful as the L.I.M. movement system has a learning curve. The included tools — a small screwdriver and spanner — are the only tools needed. No additional equipment is required.
The finished robot is surprisingly solid for its size. The plastic parts are not flimsy and the metal fasteners hold well with normal use. The motor is strong and the wheels underneath the feet create stable movement on smooth floors. Carpet can affect movement significantly — these robots work best on hard floors.

Check current Amazon prices for both robots before buying.
- You prefer red or warm colours
- Socket is cheaper on the day you buy
- You want the slightly longer build session
- You prefer blue or cool colours
- Basher is cheaper on the day you buy
- You want to get to the play phase faster
⚙ Best choice: Buy both
The robot interaction feature when two Micronoids are together is genuinely the best part of the experience. They detect each other, move toward each other, and dance in sync. If budget allows, both together is where the real fun is.

6 If This Is Not the Right Set
If you want a more advanced motorized Meccano build, the MeccaSpider is the next step up — articulated legs, sensors, and programmable behavior in a larger, more complex build.
If the robotics angle is less important and you want a classic motorized construction set with more build variety, the Super Construction 25-in-1 gives you 25 different motorized builds from 600 metal parts.
